Perhaps you should try some spelling variations:
"modified policy optimisation algorithm" » "modified policy optimization algorithms", "modified policy estimation algorithm", "modified policy estimation algorithms", "modified policy optimization algorithm", "modified topology optimization algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning method algorithm\") OR (\"modified policy optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified policy optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified policy optimisation algorithm"))*.
